Stacks?

[into-the-rv]

Hello all,

Is there anyone who has experience with what happens over the long-term when you tow an RV with a truck that has this exhaust mod?

I'd be worried about possibly getting those black shadows you see on the trailers pulled by commercial semis.

into-the-RV, I have not seen many p/u trucks with stacks and I expect that you indeed have a valid concern.

Now those OTR trucks run many thousands of miles 6 to 7 days a week unlike RV'ing which on the average an owner may only clock up 3,000 to 5,000 miles per year. I would not be too far off track if I suggested that you should not see intense streaking however I would keep an eye on it.

If you have a 2007 - 2010 truck the exhaust plume itself would be significantly cleaner as well due to the emissions controls.

IF you keep a good UV polish on the rig, it should not stick and wash off easily.

My son has 6" dual stacks on his 2001 F-350/7.3L Diesel that stick up just beyond the cab height. Now, his is highly modified and makes a ton of smoke under heavy throttle. When he floors it the smoke rolls downward on an angle just over the tailgate which would hit right on the front of your 5'er. So I'm not sure that stacks are going to solve your concerns.

Hi Newmar, just like your description I was envisioning stacks as possibly causing the problem.
